Pulling back the hammer then the slide
Can any damage come from cocking the hammer before pulling the slide back to chamber a round?
I can't think of a reason why there could be any damage but I'm not as knowledgeable about firearms as I'd like to be yet.

No. You're doing MANUALLY what the slide does automatically (if the gun isn't DA Only) when it's fired.
Cocking the hammer manually makes racking the slide easier for those who find it a challenge, as you're then compressing only one spring at a time - - hammer spring, then recoil spring-- rather than both of them at the same time. |

re:
Just don't overcock the hammer and let it slip. If that happens, it falls directly onto the sear with full force. When the slide cocks it, the hammer is lowered back to the sear gradually and more slowly. I whenever I see somebody flicking a cocked hammer.

That's what I thought but wanted to make sure. Thanks a lot

For Pete's sake be careful!
You will be cocking the hammer on a gun that is loaded!!!
Well, you think it is not loaded since you are trying to load it, but "All guns are loaded when you pick them up, until you check to see that they are not." So I do not recommend that method. Although having a pistol with a firing pin block will help reduce the chances of getting a loud and unexpected sound. Notice how I skated around the argument of accidental discharge versus negligent discharge? Bart Noir

I have weak hands/arms. Cocking the hammer first on my Hi-Power was the ONLY way I could pull the slide back.

It is a way for women and men with weaker hands to rack the slides of blowback guns like the PPK/s. My wife couldn't rack the slide at all until I showed her that. Of course one must point the muzzle in a safe direction while doing it, but that goes with all gun handling, we try our best to keep the muzzle from sweeping our friends, and if we accidentally shot our enemies we'd go to jail.

The hammer hooks/full cock notch can only be so "beefy." The width of the hammer is one limiting factor, and the longer they are, the further the sear has to move to release the hammer. Long=Creep. The hook surface to sear crown interface is narrow. Otherwise, the trigger action will require a bit of effort. Designed to operate under friction...not impact.

I pull back the hammer first when using my Kadet 2 kit on my CZ... mainly because you can't get a full over the top grip due to the way it's built. It's easier to just cock the hammer and then rack the slide with my fingers.
So far so good no damage that I can see. Though I don't cock the hammer and let it fall I ease it back until it locks up on its own. |

"The hammer doesn't remain in contact with the slide, but is rather slammed backward...bounces off the grip safety tang...and falls back to the slide, striking it roughly at the junction of the stop and the center rail, assuming that the mainspring is to spec and in good shape"
That all seems to be rather violent and the assumption then is that the hammer hits the center rail just before it engages the sear so that there's no damage to it as in "letting it slip",not that I do or even think it's ok to do that. But I probably think too much about these things. Last edited by polyphemus; January 25, 2013 at 08:06 AM. Reason: typo |

This also ties into the myth of the 1911 firing out of battery and blowing up. It can't do that. It's mechanically impossible. With the slide .100 inch out of battery, the upper lugs are still engaged and the breech can't open even if it could fire...which it can't because at .100 inch out, the face of the hammer can't reach the firing pin. And...If the original 5/64ths firing pin stop radius is in play, it can't hit the pin at .090 inch out. Back the slide up a 10th inch and look at the hammer and firing pin. So, when somebody has a kaboom and offers the out of battery explanation, you know that what really happened was probably a double charge, or maybe they severely compromised the case head support during a double throwdown ramp'n'throat job. But firing out of battery? Nah.

Hammer Slap
Movin' along...
It's all about impact. Sear and hammer hook interface do well with friction. With impact...not so much. Back in the days when the AMU armorers were setting the standard, some of them did a little modification to the hammers to shorten the distance that they traveled before hitting the sear after the slide let'em go. This was done in order to preserve their 56-ounce trigger jobs by minimizing impact as far as possible, thus protecting the finely-honed sear crowns and the shortened hammer hooks. It was a fairly tricky modification to get the hammer geometry just right without going too far and letting the hammer hit the sear after the rebound. If the CZ hammer geometry is providing that minimal distance and impact, it's for a reason...and that reason is protecting the sear crown and the hammer hooks from damaging impact.

On every auto with a hammer that I know of (and that's a few), cocking the hammer first does reduce the force needed to pull back the slide. For some people, that can mean the difference between being able to cycle the slide, or not.
Yes, pulling the hammer all the way back and letting it drop onto the sear is a bad thing. But how many people are actually going to do that, especially once they understand how it is a bad thing? Most will just pull back until it "clicks" at full cock, or (as I do) pull past the full cock click, then ease it down until held. Yes, it could slip, and that's a bad thing, but anytime a hammer slips, its a bad thing, now isn't it?
